  • A good shape of magnet for mounting into a hole. Use epoxy glue, or jam in an undersized hole.
  • About 10 times more pull than the traditional, grey, ferrite type
  • This type of magnet never weakens with age
  • Triple plated for durability: Ni/Cu/Ni

Potential Uses:

  • Ideal size for making a "magnetic grate" to remove steel from flowing material. Google it along with "K&J"
  • Clamp components while gluing
  • Locate wall studs
  • Industrial fixtures
  • Frictionless spring - tension or compression
  • Attaching items firmly to steel surfaces
  • Over-riding relays.


  • Not for kids! Two or more, if swallowed, can lethally puncture gut tissue.
  • They can pinch skin and cut clothing.
  • The material is brittle. It can chip or break during collisions. Eye protection advised.
  • For credit cards, pacemakers etc, keep at a distance where the field is negligible.
